Introduction: Why users change fonts to Poco X3 Pro
Xiaomi Poco X3 Pro, with factory-fabricated settings, uses the Mi Sans brand font — concise and readable, but not always in line with users’ tastes. Some want to add personality to the interface, some want a font with better readability with low vision, and some just get bored with the standard look. Unlike Xiaomi’s flagship models, where the choice of fonts is wider, the Poco X3 Pro with MIUI 12/13 options are limited — but this does not mean that a change is impossible.
In this article, we will discuss three working methods: official (through themes), semi-official (through ADB) and informal (third-party applications). Each method has its own nuances, from simplicity to the risk of disrupting the stability of the system. For example, after updating MIUI to version 14.0.4.0.SJUMIXM (Android 12), some users encounter a font reset bug to the standard one, which is important to consider when choosing a method.
Before you start, make sure that your Poco X3 Pro:
- 📱 Version. MIUI at least 12.0.3 (checked in Settings) → The phone)
- 🔋 Battery charge above 50% (for reboot methods)
- 📁 Backup of important data (in case of failure)
Method 1: Officially change the font through MIUI themes
The safest method is to use the built-in functionality of the Themes. Xiaomi offers a limited set of alternative fonts, but they are enough for basic customization.
Algorithm of action:
- Open the Themes app (the icon with a brush on your desktop).
- Go to the Font tab (may be in the Profile → My Topics section).
- Scroll through the list of available fonts. on Poco X3 Pros are available: 🔤 Mi Sans (standard) 🔤 Roboto (classic Android) 🔤 SF Pro (similar to iOS font) 🔤 Noto Sans (Support for Multiple Languages)
Apply
Limitations of the method:
- ❌ No way to download custom fonts (only preinstalled ones)
- ❌ After updating MIUI The font may be reset to standard
- ❌ Not all system applications (e.g., Security) support font change.
Check the MIUI version (not lower than 12.0.3)
Make sure the “Themes” app is updated

Method 2: Install custom font through ADB (without root)
For users who don’t have enough standard options, there’s a semi-official method using Android Debug Bridge (ADB) that allows you to install any TTF/OTF fonts, but requires a computer connection and basic command line knowledge.
Step-by-step:
- Download and install: 🖥️ ADB Tools for Windows/macOS/Linux 📱 Turn on Debugging. USB Poco X3 Pro: Settings → The phone. → Version. MIUI (press 7 once to unlock the Developer Settings, then Settings → Additionally. → For developers → Debugging by USB
Connect your phone to your PC
Download the font.

ADB
Open the command line.
ADB
adb devices(Your device should be displayed)
adb push custom_font.ttf /sdcard/adb shellsu(If you ask root, skip this step – the method works without it)
mount -o rw,remount /systemcp /sdcard/custom_font.ttf /system/fonts/chmod 644 /system/fonts/custom_font.ttfrebootImportant observations:
- ⚠️ On some versions MIUI folder /system/fonts/ It's written-protected. In this case, you'll need Magisk to get root.
- ⚠️ Not all fonts correctly display Cyrillic or special characters. Before installing, check the font on fontdrop.info.

Method 3: Third-party applications (with risks)
For those who don't want to mess with ADB, there are apps like iFont or FontFix that simplify the process, but have significant drawbacks:
| Annex | Needs root? | Support for MIUI | Risks. |
|---|---|---|---|
| iFont | ❌ No, but the functionality is limited) | ⚠️ Partial (may not work on the MIUI 13+) | Resetting font after updating |
| FontFix | ✅ Yes (for full functionality) | ✅ Yes (tested at Poco) X3 Pro) | Possible artifacts in the system menu |
| ZFont 3 | ❌ No. | ❌ No (not compatible with) MIUI) | May cause system applications to crash |
If you decide to use iFont, follow the instructions:
- Download the app from Google Play.
- Select a font from the directory or upload your (.ttf)
- Press Set and follow the prompts. The app will suggest rebooting the phone.
⚠️ Note: Apps like ZFont can disrupt the work MIUI Poco X3 Pro, as they replace system files without compatibility checks, consequences ranging from interface failures to bootloop, recommend a full backup through Mi Cloud or TWRP before experimentation.
💡
Before installing custom font, check it on the Font Squirrel website – some fonts are optimized for the web only and may not display correctly in the mobile OS.
Comparison of methods: which one to choose?
The choice of method depends on your goals and technical skills.
| Criteria | MIUI themes | ADB | Third-party annexes |
|---|---|---|---|
| Difficulty | ⭐ (1/5) | ⭐⭐⭐ (3/5) | ⭐⭐ (2/5) |
| Castomy typefaces | ❌ No. | ✅ Yes. | ✅ Yes (limited) |
| Risk to the system | ❌ No. | ⚠️ Average (for errors in teams) | ⚠️⚠️ High (especially without root) |
| Reset after update | ✅ Often | ❌ No, if the font is in /system) | ✅ Probably. |
| Cyrillic support | ✅ Yes. | ⚠️ Depends on the typeface. | ⚠️ Depends on the typeface. |
For most Poco X3 Pro users, the best solution is a combination of Method 1 (Themes) and Method 2 (ADB):
- 🔹 First try the standard fonts from the themes.
- 🔹 If you do not have the result, install the custom font through ADB (rootless).
- 🔹 Leave third-party applications for last resort or for temporary use.

On Poco. X3 Pro MIUI 13+ method ADB may require the signature verification to be disabled MIUI Adb shell settings put global miui_optimization_disabled 1 before the beginning of the procedure.
Solving problems after changing the font
Even if you follow the instructions correctly, you can fail, and let's look at the typical problems and how to fix them:
1. Font reset after MIUI update
This is a common situation, as system updates overwrite files to /system/fonts/.
- 🔄 Repeat the installation procedure through ADB.
- 📁 Save a font backup in the cloud (like Google Drive) for quick access.
- 🛠️ Use the FontManager Magisk module (root required), which saves fonts between updates.
2. Hieroglyphs instead of letters
The problem arises if the font you choose does not support Cyrillic or your language.
- 🔍 Open the font in any text editor (such as Word) and enter the text in Russian – if squares are displayed, the font does not fit.
- 🔄 Replace the font with a universal one (for example, Noto Sans or DejaVu Sans).
3. System applications do not change the font
Some Xiaomi apps (e.g. Security or Mi Account) ignore global font settings. This is a MIUI limitation, and you can only circumvent it by:
- 🔧 Root access and file editing in /system/priv-app/.
- 📱 Installation of alternative launchers (such as Nova Launcher) that allow you to customize fonts separately.
⚠️ Note: If after changing the font the phone stopped loading (hang on the logo) POCO), Try to enter Recovery Mode (squeeze the power supply) + Volume up) and run Wipe Cache Partition. If that doesn't work, you'll need to flash it over the Fastboot.
